Lime use and functionality in sulphide mineral

2019-11-1  At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated.
